The research studies self-discipline behaviour of business administration student of Rajamangala University of Technology Phra Nakhon Pha Nakorn. There are 2 main points in objective: 1) To study the power to predict student’s self-discipline behaviour by psychological characteristic psycho-situational characteristic and social characteristic in collected group and subgroups. 2) To examine the interaction between psychological characteristic psycho-situational characteristic and social characteristic that relates to self-discipline behaviour in collected group and subgroups. The survey of 400 undergraduates was conducted to assess self-discipline behaviour of students. Moreover there are 6 independent variables in this research including 2 variables of psychological characteristic (future orientation and self-control and achievement motivation) 2 psycho-situational characteristic variables (perceived self-efficacy and attitude toward self-discipline behaviour and 2 variables of social characteristic (good role model from family and supportive rearing while the dependent variable is self-discipline behaviour. Basic statistics multiple regression analysis and two-way ANOVA were used to analyse. All of the analysis was also used in both collected group and subgroup according to socio-demographic characteristic. The results of this research are as follow: 1. 6 variables in term of psychological characteristic psycho-situational characteristic and social characteristic can predict self-discipline behaviour in collected group accounting for 59.5 per cent while subgroups are between 32.1 to 44.8 per cent. The most prediction is female group. Furthermore the most significant predicting factor is attitude toward self-discipline behaviour which is in equation in collected group and subgroups and it is the first significant predicting factor in collected group and male group as well as the student group who study in first and second years in bachelor’s degree. 2. Students who have high level of future orientation and self-control and good role model from family will have great self-discipline behaviour. In fact it is found that future orientation and self-control and good role model from family disconnect with student’s self-discipline behaviour at the level of significance of 0.05. However when analysing each independent variable self-discipline behaviour varies with future orientation and self-control. It appears on collected group and 4 subgroups which consist of male group female group the first and second year undergraduate group and the third and fourth year undergraduate group. In addition good role model from family influences self-discipline behaviour that can be found in collected group and 4 subgroups such as male group female group the first and second year undergraduate group and the third and fourth year undergraduate group. 3. The students who have high achievement motivation and supportive rearing are estimated to have great self-discipline behaviour. Whereas it is apparent that achievement motivation and supportive rearing do not interact with self-discipline behaviour at the level of significance of 0.05. On the contrary when considering each independent variable achievement motivation affects self-discipline behaviour in collected group and subgroups (male group female group the first and second year undergraduate group and the third and fourth year undergraduate group). At the same time self-discipline behaviour is also determined by supportive rearing that presents in both of collected group and subgroups which include male group female group the first and second year undergraduate group and the third and fourth year undergraduate group.

This thesis proposes technical performance evaluation and economic decence for the combination of harmonic correction devices in Industry. Currently an electronic device is popularly applied in power network. Although it is a higher performance device than the existing device it still causes the power quality issues and then network failure. Especially harmonic disturbance in the network it is a harmonic source that generates harmonic current into the network. Many types and solutions are available in the present time therefore the suitable and optimal financial solution must be considered. A network model for the analysis of harmonic correction devices suitable solutions and optimal financial has been established in the simulation software that bases on the power and Break Even Point (BEP) equations. The results of analysis shown that the performance of harmonic correction devices suitable solution and BEP of investment in match to the using of a detuned filter bank and an active harmonic filter (case 8) thus these information will be valued for the end-user.

By the IoT technology used the sensor and transducer technology to record parameters for monitoring automatically many orchard. The data will show on your smart phone. We can see temperature pressure of water supply system level of water in pond this article was studied and designed to merge the IoT technology in agricultural technology. By the IoT used the sensor and transducer technology to record parameters for monitoring automatically many orchard. The data will show on your smart phone. You can see temperature pressure of water supply system level of water in pond and signal integrate to transmit data by network internet for any user can monitor from anywhere and all time. The result shown that the water control system can work actually as condition of controller and can transmit by network internet in real time.

Direct selling business has plays a vital role for generating national revenue towards Thailand economic for several decades. Particularly during last past decade direct selling business has been generating in the diversity size involved large medium and small business unites.

Five point Likert scale and closed end questionnaires were used for collecting data from executives directors of 12 direct sale companies and 400 independent distributors. The data were interpreting by using percentage (%) Mean (x) and standard deviation (S.D). The inferential statistics represented by t - test and F-test. The research finding indicated that direct sales service quality management is the important factor that can be contributing business success. Considering in detail found that the relationship between service provider (direct sale company) and service receiver (independent distributor agency customer) have a most significantly important in among other service dimensions.

Despite the overall picture of direct sale companies in Thailand have providing promotional services to the independent distributor in order to meets the standards of the direct sale association development of Thailand. Addition the objective of this association is for enhance direct selling business standard simultaneously generated the confident of new comer businessmen and customer in direct sale business network. Hence promoting business development plan is requiring the expertise person who have been in this particular area of business to supervise of business outline under the framework of direct sale association development of Thailand Key words : The direct selling business
